COMBINED SPRING AND FRICTION DRAFT RIGGING.

SPECIFICATION formingpart of Letters Patent No. 701,514, dated June 3, 1902.

Application filed September 28, 1901. Serial No. '761 4- (N mod l- To ctZZ whom it may concern:

Be it known that I, CHARLES S. SHALLEN- BERGER, of the city of Milwaukee, State of Wisconsin, have invented certain new and useful Improvements in a Combined Spring and Friction Draft-Rigging, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to a combined spring and friction draft-rigging; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

The object of this invention is to provide a simplified and improved combined spring and friction draft-rigging for cars comprising a movable friction-casing and a front frictionplate arranged to receive the draft and buff- 2o ing shocks and a spring for holding the latter plate, in combination with side friction-plates interposed between the friction-casing and the front friction-plate and springs for holding side friction-plates in position.

Figure 1 is a view showing my improved spring and friction draft-rigging with parts in section. Fig. 2 is a perspective view of the front friction-plate. Fig. 3 is a perspective view of a movable friction-casing. Fig.

0 4 isa perspective view of one of the side friction-plates.

My invention is designed to be connected with the draw-bar and holds the latter in position. It consists of a movable friction-cas- 3 5 ing supported between the draft-timbers and connected to the draw-bar by means of a yoke and a front friction-plate actuated by springs. Two of said friction-plates are interposed between the frictiomcasing and the front frico tion-plate and are yieldingly held by means of springs, so that the draw-bar can be moved without any unnecessary jar or strain upon the timbers of the car.

Referring to the drawings, 1 denotes the draft-timbers, and 2 the draw-bar. Metallic supports 3 are bolted to the inner faces of the draft-timbers and support guide plates 4, upon which the friction-plates are mounted.

5 indicates a hollow metallic casing, which is'mounted upon the plates 4 and the rear end of which is reinforced by the substantially \l-shaped ribs 6, which, as clearly shown in Fig. 1, project into the casing toward the outer end thereof. The rear end of the casing is provided with a recess 7, within which a yoke 8 rests, and the forward end of the said yoke is attached to the draw-bar 2, thereby holding the latter in position.

9 indicates a buffing or draft plate, which is mounted upon the plates 4 and against the rear end of the draw-bar 2. The buffing-springs 1O bear against the said plate 9 and against the front friction-plate 11, which rests upon the plates 4. The said plate 11 is substantially V-shaped in plan and projects into the friction-casing 5.

12 indicates the side friction plates, the ends of 'which are beveled, as indicated by 13, and which are interposed between the front friction-plate 11 and the ribs 6. The beveled portions 13 have the same angle and bear upon the plate 11 and the ribs 6. There are two of the said plates 12, one on each side of the friction-plate 11, and the ribs 6, and they are actuated inwardly by means of the strong coil-springs 14, which rest within the recesses 15, formed in the said plates 12. A bolt 16 extends through the said plates and carries on each end a plate or spring-support 17, against which the outer ends of the springs 14 bear. It will thus be seen that the plates 12 comprise yielding retainers for holding the friction-casing 5 and the friction-plate 11 apart.

The casing 5 is held in position upon the plates 4 by the lugs 18, which limit the motion of the casing. Similar lugs 19 are provided for holding the buffing-plate 9 when the outward pressure is exerted upon the drawbar. The said lugs 18 and 19 are integral with the supports 3, and hence form stationary stops for holding the movable parts in position. Guide-lugs 20 are integral with the top and bottom of the casing 5 to receive the yoke 8 and to prevent the same from lateral movement.

My improved spring and friction draft-rig ging forms a yielding connection for the drawbar and relieves any sudden jar or strain upon the car-timbers when different cars are brought together or while they are in motion. When outward pressure is exerted upon the draw-bar, the pressure is imparted to the easing 5 by the yoke 8, and in such operation the said casing is moved more or less upon the supporting-plates 4. This movement forces the ribs 6 between the friction-plates 12, separating them in opposition to their springs 14. The front friction-plate 11 also cooperates with the ribs 6 and forms an additional and final opposition, for the reason that the ends of the said plates 12 bear against the same. When the cars are suddenly brought vtogether and the draw-bar is driven under the same, the end of the draw-bar pushes against the buffing-plate 9 and the spring 10 forms a yielding stop for holding the drawbar and also bears against the friction-plate 11, forcing the same between the said friction-plates 12, which will be forced apart in the same manner as above described when outward pressure is exerted upon the drawbar. It will thus be seen that the springs and friction-plates form a yielding rigging for holding the draw-bar and relieving the car-timbers of any sudden jar or strain which will otherwise be caused by the sudden bringing together of the cars. When the parts are secured in position, it is impossible for any of them to become dislocated or'detached, and hence they form a simple, strong, and durable rigging.

I claim- 1. The combination with a draw-bar, of a friction-casing having an'integral wedgeshaped friction-plate at its rear end and arranged to slide with the draw-bar, a draw-bar connection, and the following friction mechanism all contained Within said casing a front friction-plate adapted to receive both the out- Ward and inward pressure of the draw-bar, opposite side friction plates, and suitable yielding connections for holding the said parts in proper position, substantially as specified.

2. A combined spring and friction draftrigging, consisting of a movable friction-casing having an integral wedge-shaped frictionplate at its rear end and arranged to slide with the draw-bar, a front friction-plate mounted adjacent to the friction-casing and arranged to receive both the draft and buffing shocks, two opposite movable side frictionplates mounted between the front friction-plate and the rear friction-plate, and means for holding the said parts in proper adjustment to receive the inward and outward pressure of the drawbar, substantially as specified.

3. In a combined spring and friction draftrigging, the combination of a draw-bar, amovable casing having an integral wedge-shaped friction-plate at its rear end, and arranged to slide with the said draw-bar, and the following friction mechanism all contained within said casing; a buffing or draft plate, a front friction-plate arranged to receive both the buffing and draft shocks, a buffing or draft spring interposed between the buffing-plate and the front friction-plate, two side plates interposed opposite each other between the front friction-plate and the rear friction-plate, and means for maintaining said plates in position, substantially as specified.

4:. The improved draft and buffer rigging, comprising the casing having a wedge-shaped friction-plate at one end, a wedge-shaped front friction-plate loosely arranged to slide in the opposite end of said casing, with its wedge facing the wedge of the plate first mentioned, opposite side friction-plates 12, the ends of which are beveled to engage the beveled faces of said end friction-plates, said side friction-plates having recesses 15, a bolt 16 eX- tending through said recesses, springs 14 mounted one in each recess, and a draw-bar connection whereby the said front frictionplate is adapted to receive both the draft and buffing shocks, substantially as herein specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES S. SIIALLENBERGER.
